This paper presents a solution of the selective harmonic elimination problem in multilevel converters based on an analytical formula. Three phase l-level cascaded H-bridges (CHB) inverters with l = 2s + 1, s = 2n number of both dc sources and switching angles are considered to delete n harmonics, arbitrarily chosen, and their multiple from output voltage waveform, imposing the amplitude of the fundamental harmonic. The procedure calculates the unknown switching angles depending on modulation index.

Abstract

This paper presents a solution of the selective harmonic elimination problem in multilevel converters based on an analytical formula. Three phase l-level cascaded H-bridges (CHB) inverters with l = 2s + 1, s = 2n number of both dc sources and switching angles are considered to delete n harmonics, arbitrarily chosen, and their multiple from output voltage waveform, imposing the amplitude of the fundamental harmonic. The procedure calculates the unknown switching angles depending on modulation index.
